Title: Improvements in or relating to electric circuit interrupters
IPC: H01H33/14
Filed: 1956-04-05
Abstract: 788,835. High-tension switches. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. April 5,1956 [April 15, 1955], No. 10426/56. Class 38 (5). A casing 2 filled with gas, preferably sulphur or selenium hexafluoride, has a number of U- shaped movable bridging contacts 40 mounted on a rotatable insulating drive-shaft 38 pivoted at 21 and 38a. The fixed spring-loaded butt contacts 72 are mounted on an insulating bar 77 and surrounded by cylindrical polytetrafluoroethvlene shields 78. The fixed contacts of breaks B, C and D, E are joined by strips 82 so that anticlockwise rotation of the shaft 38, from the position shown, produces six breaks in series. Plate 49 at the top of the unit covers the whole contact assembly so that any condensate that forms does not fall on the contacts but passes over plate 48 and through aperture in plate 50 into a sump where the condensate is heated (Fig. 2, not shown). In an alternative arrangement, Fig. 14, the drive-shaft is fitted with a piston wing 89 which on circuit opening compresses the gas between insulating plates 95, 96 and forces it through apertures 105 into the contact chambers 92 and along the arc paths when the contact ends 71a pass through orifices 104 in the polytetrafluoroethylene shields 102.

Abstract: 886,047. Book-keeping apparatus. EBHARDT, H., LINGELSHEIM, W. VON, EHRLICH, H., and EBHARDT, H., [trading as KONIG & EBHARDT GESCHAFTBUCHERFABRIK, J. C.]. April 1, 1958 [April 1, 1957], No. 10440/58. Class 16 In apparatus for book-keeping, three account sheets are clamped independently on a baseplate 1 by three clamps 8, 10, and 12 which are pivoted on a shaft 14, one above the other, independently urged into clamping position by springs, and each clamp can be opened to release its sheet without causing the release of the other sheets. The clamps 8, 10, 12 are mounted on the shaft 14 by downwardly extending end portions 24, 27, 32, respectively, and each has a vertical arm terminating in a horizontal clamp plate. The vertical arms 9. 11 of the clamps 8, 10 have complementary cut-outs 30, 31 enabling these arms to rest together in the same vertical plane to serve as abutments for two account sheets which can thus be superimposed in exact register: a bar 18 secured on the plate 1 registers the journal sheet. The clamps 8, 12 are urged towards the plate 1 by leaf springs, such as 15, which are slidably fitted in slots in fixed blocks 17, and the clamp 10 has secured thereto, beneath its horizontal arm, coil springs which bear against the plate 1. This arrangement of springs enables the shaft 14 and the three clamps to be adjusted bodily along the plate 1, and to this end the ends of the shaft are mounted in end plates 6 adjustably secured to brackets 5. To enable all the clamps to be manipulated by the left hand only, the clamp 8 has a handle member 25 extending the full depth of the plate 1, and narrow handles on the clamps 10, 12 are arranged close together. Carbon paper arrangements:-Two carbon papers for insertion beneath the account sheets are each arranged in a framework of transparent plastic material, such as self-adhesive strips, the two frames being united together at their right-hand edges.

Filed: 1917-04-16
Abstract: 141,741. Dewandre, A., and Laminne, J. de. June 15, 1916, [Convention date]. Projectiles; fuses.-Relates to grenades of the kind in which the fuse is ignited by a striker in an axial tube and the detonator is situated in a tube adjacent the striker tube, both tubes opening into a disk screwed into the bottom of the grenade body. According to the invention, the striker tube is internally ribbed for guiding the striker and. venting the gases generated by the ignition. As shown, a fuse cord p connected to a detonator q and to a percussion-cap holder h is inserted into the grenade through a bottom aperture a' closed by a screw-plug a<2>. The tip of the fuse cord is coated with inflammable, paste r, as described in Specification 141,744, and the percussion-cap o is held by elastic limbs h<1> on the holder h, as described in Specification 141,743. The percussion cap is fired by a spring striker i which is guided within a tube e by ribs e', the spring taking its abutment on a washer l making a tight fit with the striker. The tube e enclosing the striker and the tube f enclosing the detonator q end in a disk g containing the fuse cord p and screwed into the bottom aperture a<1>. These parts and the grenade body a are made of cast iron, the grenade body having internal weakening grooves d. The striker i is held cocked bv a resilient external lever m locked by a safety pin n provided with a ring normally forcibly engaged by lugs a<5> on the grenade body. The lever, in the locked position, bears with its outer end on the grenade body, and by its resiliency presses outwardly on the safety pin, thus prevent accidental unlocking, as described in Specification 141,742. When the striker is released and thrust by its spring against the percussion cap, the gases from the fuse escape easily past the ribs e' around the striker and out by the hole a<3> now no longer closed by the striker.

Title: Improvements in electronic counters and accumulators
IPC: H03K23/82
Filed: 1954-04-13
Abstract: 759,547. Electronic counting-apparatus. INTERNATIONAL BUSINESS MACHINES CORPORATION. April 13, 1954 [April 16, 1953], No. 10828/54. Class 106 (1). An electronic counter comprising a plurality of cascadecoupled bi-stable triggers (each containing two triodes) is characterized in that it also comprises electronic means for generating a first impulse, network means responsive thereto to produce a second impulse, means for transmitting said first impulse to change the stages of certain of the triggers and means for transmitting said second impulse to change the states of the other triggers for manifesting the complement of a number registered on the counter. Each denomination of a decimal accumulator, only the first and last of which are shown, comprises a counter consisting of four bi-stable triggers, 1-4, which when " on " (left-hand side conducting) represent the values " 1 ", " 2 ", " 2 ", " 4 ", repectively, and includes a rectifier in stage 2, which, when trigger 2 is " off " (righthand side conducting) permits a negative pulse from trigger 1 to pass direct to trigger 3, via line 32 and a feed-back connection, line 50, from stage 4 to stage 2. In each counter the nines complement of a registered number is obtained by changing the state of every trigger, and this is done by causing a thyratron 5 to fire and to lower the voltage on each anode, but because of the unsymmetrical connections to trigger 2 there is a risk of inter-stage pulses nullifying the effect of a lowering of the anode voltage. This risk is prevented by tapping the anode load of the thyratron 5 at two points 7, 8 so that when thyratron 5 fires negative-going pulses are transmitted along lines 13 and 34, that along line 34 to trigger 2, being the sharper, i.e. the voltage at terminal 49 rises more quickly to its former level than do the voltages at terminals 19 &c. Thus for example, suppose trigger 1 is " off (righthand side conducting) trigger 2 is " off ", and trigger 4 is " on ", then if similar negative pulses were applied to each trigger (i.e. if terminal 49 were connected to line 13, not as shown) as the voltages on the coupled anodes began to rise there would be, simultaneously, a positive pulse applied at grid 57, from trigger 1 via lead 32, and a negative pulse applied at grid 55, from trigger 4 via lead 50, and these pulses together might be strong enough to prevent trigger 2 changing its state, whereas, when a sharper pulse is applied to trigger 2 (i.e. when terminal 49 is connected as shown) the inter-stage pulses from triggers 1 and 4 find, when they arrive at trigger 2, that it - has flipped over to the " on state, and is actually in a state where grid 57 is more negative than cut-off and grid 55 is slightly positive (this is due to the " momentum " acquired by trigger 2 in flipping over). During the inversion operation a tube 80 is rendered conductive to block accumulator interdenominational carry.

Title: Improvements in alkenylpyridine synthesis
Inventor: WHITE DONALD HENRY
IPC: C07D213/127
Filed: 1958-04-03
Abstract: Alkenylpyridines are produced by heating a crude alkylpyridine under pressure, reducing said pressure to evaporate at least 90% of the alkylpyridine from the crude feed in a first zone, catalytically dehydrogenating the evaporated alkylpyridine in a dehydrogenating zone, steam stripping the unvaporised material from the first zone and mixing the effluent material drom the stripping step with the dehydrogenated pyridine, fractionating the thus formed mixture to separate unreacted alkylpyridine, recycling the unreacted alkylpyridine to a point upstream of said first zone and recovering alkenylpyridine from the bottoms of the fractionating step.  The invention also includes the apparatus when used for carrying out the above process for the production of alkenylpyridines.  The process is of particular importance when applied to the production of 2-methyl-5-vinylpyridine from 2-methyl-5-ethylpyridine.  Other compounds which may be produced from the corresponding saturated compounds are, for example, 3-vinylpyridine, 3-vinyl-4-methylpyridine and 5-isopropenyl-2-methylpyridine.
